問題文
A district heating platform receives one reading per minute from each meter. About two percent of the readings arrive with a value of zero that the meters emit while they restart. Analysts average all stored values by hour. What should the team do about those zeros?
選択肢
- Invalidate the restart readings during ingestion so that hourly averages describe the heat that was delivered.
- Exclude the restart values during analysis so that hourly averages describe the heat that was delivered.
- Replace the restart values during aggregation so that hourly averages describe the heat that was delivered.
- Shorten the reporting interval during operation so that hourly averages describe the heat that was delivered.
